Hey guys, I have a 2004 Disco that has 165k miles on it. Over the last couple of weeks it has stopped letting me fill the gas tank completely full. When I get about 16-17 gallons in it she stops taking fuel. When I crank up it shows just a touch over 3/4 full. What is the deal? This is aggravating as I have to stop even more often to fill it up. Thanks, Keith
